Description

Technical Field

[0001] This utility model relates to the field of cold heading machine tool technology, and in particular to a high-precision cold heading machine tool for the production of precision roller shafts. Background Technology

[0002] High-precision cold heading machines for precision roller shaft production are key pieces of equipment specifically designed for roller shaft manufacturing. Roller shafts are the core supporting components of various rollers. The cold heading process involves applying pressure to a metal blank at room temperature using a mold, causing it to undergo plastic deformation within the mold cavity, thereby quickly forming the desired roller shaft shape. With the rapid development of industrialization and intelligence in modern society, higher demands are placed on the performance and reliability of various mechanical equipment, leading to a surge in the demand for precision and durability of roller shafts. High-precision roller shafts can reduce frictional losses during roller operation, lower noise, and improve equipment operating efficiency and service life. High-efficiency cold heading machines can meet the large-scale, high-quality demands of the manufacturing industry for roller shafts, helping enterprises improve their production capacity and stand out in fierce market competition.

[0003] Cold heading machine tools have a short die life. Due to the extremely high pressure and friction that the die is subjected to during the cold heading process, frequent impacts can easily lead to wear, deformation, or even cracking of the die surface, reducing the service life of the equipment. Existing machine tools use lubrication structures to protect the equipment and employ sophisticated automated structures to ensure work efficiency and product quality. However, these machine tools require die replacement when processing different parts, which can cause production interruptions and reduce production efficiency. Furthermore, the continuous use of lubricating oil can increase material costs and introduce processing debris into the equipment, affecting equipment safety and making it difficult to meet usage requirements.

[0039] Working principle: A mold frame 3 is set on the machine body 1, and a sliding groove 4 is opened on the inner wall of the mold frame 3, so that the mold part 6 can be slidably inserted into the mold frame 3 through the slide bar 5. Since the connecting block 10 is fixed on the mounting block 11, and the sliding column 8 fixed on the connecting block 10 is slidably connected to the connecting plate 7 fixed on the mold frame 3, the mounting block 11 can be pushed open when the mold part 6 is installed and inserted. When it reaches the set position, the spring 9 on the outer wall of the sliding column 8 resets the mounting block 11, and the limiting strip 12 on the inner wall of the mounting block 11 locks the limiting groove 13 opened on the mold part 6 to prevent it from falling off. At this time, the locking block 14 threaded on the mold part 6 is tightened so that it is close to the pressing mounting block 11 to lock the structure. This structure can quickly disassemble and replace different molds, and the structure is simple and stable, which improves the convenience of replacement, thereby improving work efficiency and meeting the needs of quick mold replacement.

[0040] By creating an inclined groove 202 on the support platform 201, the lubricating oil in the machine tool can flow along the inner wall of the inclined groove 202. Since the front end of the support platform 201 is fixedly connected to the recovery box 203, and a recovery port 204 is created on the recovery box 203, the lubricating oil can flow into the box from the recovery port 204. A filter plate 205 is also installed on the inner wall of the recovery box 203, so that the machining debris is filtered out. Since a sliding rod 206 is fixed on the recovery box 203, when the debris accumulates, it pushes the cleaning brush 207 to adhere to the surface of the filter plate 205, pushing the debris towards the cleaning inclined surface 208 and discharging it from the cleaning port 209. This structure can recycle and reuse lubricating oil, reduce costs, and clean up the machining debris, thus meeting the recycling requirements.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
